Supports Healthy Degradation of Food-Derived Histamine!

Histamine Block by Seeking Health contains a patented enzyme formula providing 10‚000 HDU of diamine oxidase (DAO) - the main enzyme responsible for the degradation of ingested histamine - per capsule. Histamine is known as a biogenic amine‚ an organic nitrogen compound‚ involved in certain immune responses and found in mast cells. It may be involved in regulating healthy function in the GI tract as well as the nervous system. Histamine also plays an important role in triggering the body’s normal inflammatory response.

      Recommended Brand of this product

      from WEST PALM BEACH FL on 7/22/2022
      I can't tell if it is helping, but everyone says this is a good brand of DAO.



      Pricy, but maybe it is expensive to produce.

      I take one capsule before eating dairy. I have an allergy to casein, the protein in dairy. These solve the problem!


      These work!


      I have no complaints.

      Great Product

      from IL on 1/01/2022
      This product is great. The only reason I did not give it five stars is because it is so expensive. I wish a company could make a histamine blocking supplement that would be affordable to everyone. At $0.85 a pill, it really adds up when you have to take it at every meal.


      It helps with histamine food intolerances.


      Way too expensive!

      Great Product

      from Alaska on 10/05/2021
      Used last month and found it helped me avoid bad sinus problems and head fog associated with eating certain foods. I also added Quercetin and Bromelain to the mix, and now my nose is as dry as a whistle!


      Works well, improves quality of life with allergies


      Wish I could get more capsules for the $$$

    • Great Product!

      from Ocala on 6/13/2021
      I take to tablets before I eat to control histamines. For me it prevents getting an irregular heartbeat.


      It works every time.


      If I forget to take it, I get an irregular heartbeat.

    • Good product, great packing

      from Maryland on 2/26/2021
      I take Histamine Block for histamine intolerance and it's very helpful. My order arrived promptly. I want to commend Pure Formulas for using 100% biodegradable paper packing - wish more companies would do this.


      It works to stop the symptoms of histamine intolerance

    • Gives back freedom to eat with others

      from Alaska on 1/15/2021
      One pill taken 10 min before a meal greatly reduces the histamine reaction I would normally have with certain foods. This allows me to eat at parties or restaurants when I don't know exactly how things have been prepared. All but the strongest of my chemical sensitivities are undetectable when taking Histamine Block. One warning: it really does have to be taken before I eat to offer the full benefit. I have sometimes forgotten until halfway through the meal and I can end up with a headache or patch of hives anyway, so keep it in the kitchen or on your person when you are out. Its easy to forget.


      I like that I can take this and it helps even though I still have histamine intolerance. It improves my quality of life NOW, even as I work to repair the cause of my issues. It does not cure any condition, but it allows me to go out with friends and share in the traditional family meals, such a gift during the holidays especially. It becomes very tiresome to always be eating something different from everyone else.


      It is still expensive per pill. This was an excellent price compared to what I've seen elsewhere, or for similar products, but it still adds up if you take it very often. I usually take only one or less per day unless I am traveling or staying with others and have no control over the foods I am given.
